Cylinder, with slide valve removed to show ports A double-acting slide valve cylinder. Steam enters via the steam port SP, and is admitted by the slide valve SV through the upper passage S to push down the piston P. At the same time, exhaust steam from below the piston passes back up the lower passage S, via the valve cavity, to exhaust E. As ...
Therefore, the application of a booster engine to the previously unpowered axle meant that overall starting tractive effort was increased with zero penalty to the adhesion levels of the main engine. Additionally, the "gearing" of a steam locomotive is fixed, because the pistons are linked directly to the wheels via rods and cranks.
The diagram, which is not to scale, is a composite of various designs in the late steam era. Some components shown are not the same as, or are not present, on some locomotives – for example, on smaller or articulated types. Conversely, some locomotives have components not listed here.
The B class are a class of diesel locomotives built by Clyde Engineering, Granville for the Victorian Railways in 1952–1953. Ordered and operated by the Victorian Railways, they initiated the dieselisation of the system and saw use on both passenger and freight services, with many remaining in service today, both in preserved and revenue service.
Diagram of a Fairlie locomotive. A Fairlie locomotive is a type of articulated steam locomotive that has the driving wheels on bogies. It was invented by Robert Francis Fairlie. The locomotive may be double-ended (a double Fairlie) or single ended (a single Fairlie). Most double-ended Fairlies had wheel arrangements of 0-4-4-0 T or 0-6-6-0 T.
Double-beat poppet valves became widely used during the nineteenth century. Francis Stevens invented the Stevens valve gear, a double beat poppet valve, in 1839. It was used throughout the nineteenth century and in the early years of the 20th, on side-wheel paddle steamer engines, including the grasshopper engine, in the United States. [4]
The SD50 was produced in response to increasingly tough competition from GE Transportation, whose Dash 7 line was proving quite successful with railroads. While EMD's SD40-2 was a reliable and trusted product, GE's line included locomotives up to 3,600 hp (2,685 kW) with more modern technology, as well as very competitive finance and maintenance deals.
Bowser Manufacturing is a United States manufacturer of model railroad equipment, located in Montoursville, Pennsylvania.Founded in 1946 by Bill Bowser in Redlands, California, he used his skill as a machinist to design and produce one of the first lines of accurately scaled steam locomotive kits in HO scale.
